Canon EF 16-35mm USM Ultra Wide Angle Zoom Lens
With the capability of switching from the ultra-wide 16mm to a wide 35 mm, this Canon lens is an excellent wide angle option. While it has the versatility of a zoom, it's still relatively fast at f2.8, so it will still perform well when the lighting is limited. Designed for professionals, it has Canon's best lens elements for edge to edge sharpness. The autofocus motor is quiet, yet fast and the internal focusing design means the length of the lens doesn't change while the lens is focusing. Full time manual focusing is also available. Close-ups are possible too, with a minimum focusing distance of just under a foot.
